We experimentally demonstrate silicon ring resonators with internal quality factors of Q0=2.2×107, corresponding to record 2.7dB/m propagation losses. Importantly, we show that these propagation losses are limited by bend loss, indicating that the propagation loss limit for silicon has not yet been reached.
